How is water interconnection carried out for low-temperature methanol washing in winter? What issues should be noted? It’s pretty cold in our northwest area! !
It’s better not to do it! The consequences are severe if the water cannot be purified. If you want to do it, add additives such as methanol or ethanol to the water, which can lower its freezing point. Proper drainage must be ensured for the left posterior lobe.
It has no impact; add methanol as soon as possible after the water-methanol transfer is complete, and then carry out one cycle with methanol. Any remaining water will be treated in the methanol-water separation tower.
Replying to the person above: It’s a great idea, but many unforeseen issues will arise when trying to put it into practice. Also, how long does it take from starting the drainage to establishing a methanol cycle?
May I ask which company the original poster works for? We have also used water transport in winter; there was no problem. Our water intermodal transport period was short, so the equipment wasn’t greatly affected.
Running water continuously will not freeze, and its temperature will increase over time; just make sure there are no dead corners when draining it
Be careful to prevent freezing; it is advisable to run a methanol cycle after the water transfer process. This helps to prevent the equipment from being damaged by freezing due to incomplete drainage, and it also allows the dehydration system to reduce the water content in the circulating methanol to below the specified level, achieving two goals at once; If the methanol circulation cannot be started immediately, it becomes a bit troublesome to drain all the water from the equipment and pipelines, which requires care and patience :)
